Abstract (en)

[origin: US2005283149A1] An electrosurgical instrument is provided. The electrosurgical instrument includes an active electrode in close proximity to a return electrode. The active electrode has a first thermal diffusivity. The second electrode has a second thermal diffusivity greater than the first thermal diffusivity. The volume, shape, and thermal diffusivity of the second electrode facilitate the transport of heat.
